VANNlNG-MACHINE AND CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 565,355, dated August4, 1896.

Application filed July 10, 1893. Renewed March 6, 1896. Serial No.582,072. (No model.)

To all whom it may concern.-

Be it known that I, WVILLIAM HORACE HOOPER, a citizen of the UnitedStates, and a resident of Empire, county of Lewis and Clarke, State ofMontana, have invented a new and useful Improvement in Vanning-Machinesand Concentrators, of which the following is a specification.

In vanning-machines it is customary to pass the belt through awashing-box beneath the machin e,in which the concentrates are washedfrom the belt by the action of the water. These concentrates are thendrawn from the washing-box with a hoe into another box, in which or fromwhich they are carried away to the place of storage.

My invention is intended to obviate the labor of moving the concentratesonce by removing the great bulk of them from the belt before it reachesthe washing-box. It consists simply in a roller hung beneath and incontact with the belt a short distance from the head-roller, and in thepeculiar character of the hangers supporting it. I show it in connectionwith the Frue vanning-machine.

Similar letters refer to similar parts in all the drawings.

Figure 1 shows an elevation of head-roller and cleaning-roller. Fig. 2shows an end elevation of same. Fig. 3 shows a perspective view ofhanger and part of cleaning-roller.

Fastened to the frame I at a short distance from the head-roller K, bythe bolts H H, are the hangers D D, slotted at their upper ends andhaving a slotted step E, turned inward at right angles, at their lowerends. The rod G runs across from hanger to hanger, threaded at each endfor a short distance, and stiffens the hangers.

On the step E plays the half-round box or bearing 0, having the tongue Fto run in the slot 6.

The cleaning-roller A, of the width of the belt inside the raised edgesZ Z, works in the boxes 0 O at its bearings B B, which are provided withthe shoulders I) b. Beneath the cleaning-roller A is placed the box Mfor catching the concentrates.

In operation the hangers D D are so adj usted as to place thecleaning-roller, preferably made of wood, a little forward of theperpendicular from the bolt H to the belt L, and so as to raise the beltslightly at the point of contact. The slot in the hanger D permits suchadjustment, and the position is secured by the bolt H, the nut h, andthe Washer 71. The cleaning-roller turns with the belt to avoid frictionand wearing. The box 0 moves freely upon the step E the length of theslot 6, and thus permits the cleaning-roller A to adapt itself to anyside motion of the belt L occasioned by the shaking motion of the frameI.

This attachment may be used with any vanning or concentrating machineusing the continuous belt. Its working is very simple and effective, andconsists in producing a dam or obstruction against the belt, holdingback the water clinging to the belt, whereby the concentrates come offreadily from the belt with the Water and drop freely into the box M.

The belt should still be passed through the washing-box to secure anymatter not removed by the cleaning-rolle'r, but there will be butlittle, and the labor of drawing out the concentrates from thewashing-box is practically dispensed with.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a vanning or concentrating machine, the combination with the beltand its carrying-rollers, a tank for receiving the concentrates and acleaning-roller arranged in con tact with the belt so that theconcentrates removed from the belt by the cleaning-roller will drop intothe tank, substantially as described.

2. In combination with a concentratonbelt, having a smooth surface, thecarrying-rollers and a cleaning-roller placed beneath and in contactwith the belt near the head-roller, said cleaning-roller also having asmooth surface to coact with that of the belt, substantially asdescribed.

' 3. In a vanning or concentrating machine, the combination with thebelt, of the cleaning-roller, having a smooth surface, placed beneathand pressed close against the belt, near the head-roller, and supportscarrying self-adjusting bearings for said cleaningroller, substantiallyas shown and described.

ing in the same direction as the travel of the belt so as to form aWater-cushion at the point of union with the belt by which Watercushionthe sulfurets are removed from the surface of the belt.

In testimony that I claim the foregoing as my inventionI have signed myname, in presence of two witnesses, this 30th day of June,

WILLIAM HORACE I-IOOPER. \Vitnesses:
